[R-Koga] The Metal Dick (Kotori-kan Vol. 2) [YxTL]

A schoolgirl's late-night detour becomes something far more intimate when she sneaks into the empty schoolyard to indulge her secret obsession with the courtyard water faucet—its rounded metal knob serving as her personal cock. Sweating through her tank top, she rides it with escalating desperation, juices overflowing as she loses the strength in her legs, until the climactic moment she cranks the handle and lets cold water spurt deep inside. But even spent in the afterglow of her secret night, one aching want lingers: the craving for the real thing.
